Important Installation Notes
Upon installation, if the vehicle does not start, a theft relearn will need to be done using the GM programming system Tis2web/Techline Connect. Please note that this is the responsibility of the end user. We sell engine computers programmed to your vehicle’s VIN and correct calibrations; however, it is the buyer’s responsibility to perform any necessary relearns or setup procedures, such as injector setup or crankshaft variation relearn.
